Abstract: PURPOSE:To enable the high-speed switching of magnetic fields by reinforcing two high permeability magnetic materials parallel with the surface of a magneto-optical disk of a magnetic path with metals and forming the winding of a core having a hollow part as a coil formed by spiral pattern etching around the hollow part. CONSTITUTION:This magnetic field impressing electromagnet is constituted of the cylindrical high permeability magnetic material 2 which is wound with the coil 23, the high permeability magnetic material 1 which is disposed to face the magnetic material 2 with the magneto-optical disk in-between and has the spiral coil 5 formed by pattern etching around the cylindrical hollow part 21 at one end, high permeability magnetic materials 3, 4 which magnetically couple the two magnetic materials 1, 2, metallic reinforcing plates 6, 7 which reinforce the magnetic materials 1, 3 and a magnetic field generating current modulating circuit 10 which passes the same current to the coils 5, 23. The magnetic field to be impressed in the direction perpendicular to the recording medium is applied by passing the current to the coils 5, 23 by a modulating circuit 10. Since the inductance of the coils 5, 23 is easily decreased to <=10muH, the switching of several 100 oersted magnetic fields at a high speed of several MHz is enabled.

Title: Device for measuring actuator characteristic and device for correcting eccentricity using it
Inventor: SHIMIZU KEIKO
IPC: G11B7/00
Filed: 1993-06-29
Abstract: PURPOSE:To accurately correct eccentricity, to stabilize tracking control and to accelerate access operation by optimizing an eccentricity information signal gain and a phase added to a tracking control loop with the number of revolution of a CLV (linear velocity is constant) disk. CONSTITUTION:An eccentricity information signal is fetched into a third memory means 21. Then, a disturbance impression command is outputted from a disturbance impression command generation means 18 to a selection means 17 and a third read/ write control means 20, and the output of the means 17 is switched from the output of a tracking control means 7 to the output of a disturbance generation means 15, and the eccentricity information signal is read out from the means 21. Then, in the state of the off of the tracking control, an added output between the eccentricity information signal and the disturbance is impressed to a tracking actuator 4. While the impression is performed, the disk is rotated at the same number of revolution as the number of revolution when the eccentricity information signal is fetched by a rotation means 2. Thus, no gain and no phase of the actuator 4 are changed, and the measurement eliminating the effect of the eccentricity is performed, and the track traverse due to the eccentricity occurring while the disk is rotated, is prevented.

Title: Supporting leg of compressor
Inventor: ABE NOBUO
IPC: F04B39/12
Filed: 1981-10-07
Abstract: PURPOSE:To produce the captioned member out of a coil material having minimum dimensions in width in the most economical and efficient manner by using thin steel plate for reinforcing structure to withstand impact and plastic molding any rising member in a bore of supporting hole and connecting the rising member to a plane area via a joint. CONSTITUTION:Even when a considerably thin steel plate is used as a blank material the reinforcement for a plain area 11C between an outer periphery member 11d and a supporting hole 11e is sufficient, because a joint member 11g of a rising member 11f exerts practically the same effect to increase the thickness of plate by plastic-molding a material of the bore of a supporting hole 11c, which is press-punched and destined to be scrap, out of a coil material having minimum dimensions in width. Use of material thus press-punched and otherwise scraped as well as drastic reduction of the thickness of the supporting leg 11 due to the exerted effect to practically increse the thickness of the joint member 11g makes it possible to produce the captioned member out of a coil material having the minimum dimensions in width in the most efficient manner.

Title: Electric daylight window device
Inventor: ADACHI SHINJI
IPC: E05F15/20
Filed: 1995-06-26
Abstract: PURPOSE: To detect rain more accurately by providing a measuring means measuring the pulse width of the output frequency signal from a rain sensor, a calculating means, and a collating means in a controller. CONSTITUTION: The frequency signal corresponding to the present state is invariably outputted from a rain sensor 1, and it is inputted to a controller 2 via an interface 3. A CPU 5 starts to measure the pulse width based on the counting of a pulse width measuring timer counter 4, deletes multiple short pulse widths and long pulse widths from the multiple measured pulse widths, and calculates the average pulse width from the remaining pulse widths. The CPU 5 calculates the difference values from the average pulse width, compares the difference values with the detection sensitivity threshold value set by a selector switch 8 in advance. When the difference value is the detection sensitivity threshold value or above, the CPU 5 judges that the pulse width is increased by the sticking of raindrops to the rain sensor 1 as rain detection.  When the difference value is below the detection sensitivity threshold value, the CPU 5 judges that no rain is detected.

Title: Operation control device for condensing extraction turbine
Inventor: NAKAMURA KENJI
IPC: F01K7/38
Filed: 1990-06-18
Abstract: PURPOSE:To increase the amount of steam flowing through a turbine, and thereby lower bleed steam in temperature by controlling a regulating valve acting as a vacuum destruction valve provided for an exhaust chamber or a condenser when a condensing extraction turbine is in no-load running with load shutdown. CONSTITUTION:A pressure detector 21 detects the pressure of exhaust steam. A regulating valve 23 acting as a vacuum destruction valve is provided for an atmosphere opening system 22 connected to an exhaust pipe 8. When a turbine is in no-load running with load shutdown, a load shutdown command is inputted into a conditioner 25, and a regulating valve 23 is controlled to be under a pressure which is higher than the pressure of exhaust steam for normal operations but is less than atmospheric one. The amount of steam flowing through the turbine is increased much more than that for normal operations, so that the turbine efficiency at the high pressure turbine section 2 is thereby made high. By this constitution, exhaust steam at the high pressure turbine section 2, that is, bleeding steam can thereby be lowered in temperature much more than former ones.
